The hsXenCtrl package

FFI bindings to xenctrl.h and perhaps more.
The System.Xen.CBindings should provide direct access
to the C API while System.Xen will eventually provide
a higher level abstraction. This library binding
allows pure haskell programs to use XenCtrl functions;
these can be Haskell versions of xend, xm, and
virt-manager but more interesting projects are possible.
Think about a happs app controlling domains and complex
policy controls on resource (CPU, memory, PCI) uses.
